NGC 4874, the bright blob at right in this Hubble Space Telescope image, is one of the largest and most massive galaxies in the universe, known as a cD galaxy. It is more than 300 million light-years away in the Coma Cluster, a gravitationally bound collection of thousands of galaxies. NGC 4874 spans perhaps 10 times the diameter of our own galaxy, the Milky Way, and may have a trillion stars or more. [NASA/STScI/Coma HST ACS Treasury Team]
